1 Claim.

My invention relates to new and useful improvements in receptacles and more particularly to paper cups or the like intended for but a single use and adapted to be nested in stack formation so that the terminal bup may be withdrawn for use.

The principal object of the invention resides in the provision of a receptacle of the character described which is relatively simple and inexpensive in construction, being formed of relatively light material, and of a construction adapting a relatively large number to be nested in a relatively small stack thereby facilitating their use in dispensing machines and making it unnecessary for the attendant to frequently rell or replenish the dispensers.

Another object consists in providing a receptacle of the character described having advantages of both the cylindrical and fiat types previously used, the same being provided with a round normally open mouth portion and a body portion which is of substantially wedge-shape tapering downwardly to provide a flat relatively wide bottom' adapted to be engaged by the fingers when removing the terminal receptacle from a stack and while using.

Still another object of the invention resides in the formation of a cup or receptacle of the character described from two pieces of material, such as paper, one piece being folded to form the main body portion of the cup or receptacle and the other piece being folded, and attached to the body portion to provide a tight bottom therefor.

With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel details of construction and arrangement of parts described in the following specication and illustrated in the accompanying drawings, and while I have illustrated and described the preferred embodiments of the invention, as they new appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claim.

yIn the drawings:-

Fig. 1 is a side elevation of the completed receptacle or cup.

Fig. 2 is a. vertical section on the line 2--2 of Fig. 1.

Fig. 3 is a perspective showing `the manner in which the body blank is initially folded.

Fig. 4 is a plan of the blank from which the bottom is made.

Fig. 7 is a plan showing one edge of the body blank folded. 1

Fig. 8 is a fragmental detail showing a slightly modified form of my invention in which the bottom telescopes over the lower end of the body; and

Fig. 9 is a vertical section on the line 9-9 of Fig. 8.

The blank of paper from which the body portion of the receptacle or cup is to be formed is indicated at a and the blank of paper from which the bottom of the receptacle or cup is to be formed is indicated at b. The blank ais of sector shape including the arcuate top edge l, the inwardly converging side edges 2 and 3, and re- 70 cessed bottom formed by continuing the side edges downwardly below the horizontal edge 4 to provide the substantially V-shaped projections 5 and 6, the inner edges of the projections shown at 7 and 8 extending at an angle relative to the 75 horizontal edge 4. The blank b from which the bottom is to be formed is of the shape shown in Fig. 4 of the drawings and consists of the parallel edges 9 and 10 and what may be termed the notched or dished ends l1 andv 12, these notched 80 ends being formed by cutting the ends to extend inwardly from the side edges 9 and 10 towards the longitudinal axis 13 of the blank.

In forming the body from the blank a the edge 3 is initially folded as shown more partic- 35 ularly in Fig. 7 of the drawings so that the edge 8 of the projection 6 extends parallel with the horizontal edge 4. Then the side edge 2 of the blank is folded over so that the edge '7 of the projection 5 will also extend parallel with the 90 edge 4 and the edge 2 will overlap the edge 3 and be secured thereto by suitable adhesive. When thus secured a substantially wedge-shaped receptacle or cup will be formed with a normally open mouth portion 14 and a relatively wide fiat bot- 95 tom portion 15 adapted to be grasped by the iingers when removing a terminal receptacle or cup from a stack or while using.

The bottom blank b will be folded on the line 13 and inserted into the formed body portion and 100 secured thereto by means of an adhesive,I the position of the bottom within the body portion being illustrated more particularly in Fig. 2 of the drawings. While I have referred to the bottom as being inserted within the body I wish it understood that I do not limit myself to the placing of the bottom within the body after the body is formed but if found desirable the bottom may be initially formed and then the body formed therearound. By shaping the ends 11 11G and` 12. as shown more particularly in Fig. 4 of the drawings, the corners or ends of the4 bottom will contact as shown more particularly in Fig. 2 of the drawings and tightly engage the inner surfaceof the body. It will be understood that the bottom will be of such a size as to snugly t within the bottom portion of the body, as shown more particularly in Figs. 1 and 2 of the drawings and will be wedged tightly into position so that there will be no possibility of leakage in use. As shown more particularly in Figs. 1 and 2 preferably the bottom will not come to the bottom edge of the body but will be spaced slight- 1y above. This permits a tight wedge or fit of the bottom within the body.

- In Figs. 8 and 9 of the drawings I have shown a slightly modied form of the invention in which the bottom, formed from the blank shown in Fig. 4, is telescoped over the end of the body portion as distinguished from being positioned within the body as disclosed in Figs. 1 and 2. In

all other respects the formation of the receptacle or cup is the same as previously described, the only difference being, as stated, that the bottom is telescoped over the bottom end of the body as distinguished from being positioned with the body.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

A receptacle including a wedge-shaped body having a normally open mouth portion and a relatively flat bottom portion, and a closure for the bottom of the body, said closure being formed from a single piece of material folded on its 1ongitudinal center line to provide opposed wall portions adapted to be engaged with the relatively flat faces of the body, the ends of the opposed wall portions of the bottom closure being bent inwardly to close the ends of the bottom closure and to engage the ends of the relatively at bottom portion of the body.
